IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. 124,841, dated March 19, 1872.

be understood from the following general description.

Figure 1 is an end view of the device; Fig. 2, a side view of the same; Fig. 3, a side view of a part of the dasher; Fig. 4, an end view of another part of the dasher; Fig. 5, a side view of the same part represented by Fig. 4. o is a sectional view of the lid, showing a 1on- Fig. 7 is transverse section of the air-tube e.

The segmental cylinder to b of Figs. 1 and 2 is mounted upon. trunnions at g and supported by the uprights i and i. It is free to turn upon the trunnion ,I. For pouring out the milk, it is provided with a spout at f. At 0 there is an air-hole, through which air passes into the tube e. This tube 0 is fastened to the bottom of the lid 0, as rep esented in section in Figs. 6 and 7. A slot atu allows the air to pass freely into the inside of the churn. This arrangement is such that while the air passes freely into the churn the milk cannot escape out. That part of the lid represented by c is movable, and can be easily lifted off by the handle d. h is a handle made for the convenience of the operator. The dasher of the churn consists of two parts, one of which is represented by Fig. 3. This piece consists of a plain board, m, perforated as represented in the drawing, and fastened in the frame I, as represented. At a is cut a notch which is intended to fit the notch n of Fig. 5. Inside grooves in the heads a of the churn accommodate the frame 1. The other piece of the dasher is represented by Figs. 4 and 5. Two perforated pieces of wood, represented by 0 and 0, are fastened together by the circular segment 1), as represented in the drawing. q and q are two sections of tube. They consist each of a longitudinal section of a cylinder, with a semicircular disk in each end so arranged as to close up the end to the edge of the section. They arefastened in the segment 12 by the plugs r parallel to the perforated boards o and 0, as represented in the drawing. The angle of inclination of the segment should be about like that represented in the drawing. The piece represented in Figs. 4: and 5 is first put into the churn, so that the ends of the boards 0 and 0 will be against the insides of the churn-heads a, the exterior curve of p resting upon the interior curve of t. The part represented by Fig. 3 is now slipped down in its grooves in the inside of the heads of the churn, with the notch a down. The grooves are to be so arranged that n will fall into and rest on a, and in this way both parts of the dasher will be held securely in the churn.

The milk is now put in and the lid 0 put on. The operator grasps the handle it and oscillates the churn from side to side, turning it around the trunnion g. This motion will compel the milk to run back and forth through the perforations 0 0 and m, which will greatly agitate the fluid. The segmental tubes q and q, while they are carried back and forth by the oscillation of the vessel, will sometimes be in the air and sometimes in the fluid. As they come into the air they receive a store of it, which they,

by their arrangement, diffuse gradually in bubbles as the milk flows over them, thereby greatly assisting the agitation of the fluid and facilitating the process of making butter.

I do not claim an oscillating churn consist ing of a cylindrical segment; but

I do claim- 1. The combination of the dasherboards 0, 0, and m, the segmental tubes q and q, the plugs r and r, and the circular segment 12, for the purpose and in the way substantially as set forth.

2. The combination of the lid 0 with its air tubes e,the dasher-boa-rds 0, 0, and m, the segment 10, the segmental tubes q and q, and the plugs r and r, for the purpose and in the way substantially as set forth.
